I sold a text book on this past weekend and bought the postage ($8.50 Priority Mail) and printed the shipping label using Pay Pal. I had forgotten about the postage rate increase but for some reason I decided to take the package to the counter at the post office just to double check that I had enough on it and man did I get a surprise! I ended up paying an additional $3.40 more for postage for the one package!

Cheers!
Bill
